Question

Find the value of ‘k’ if the lines 6x – 10y + 3 = 0, kx – 5y + 8 = 0 are parallel.​

Answer 1

Answer:

as there are no solutions(lines are parallel)

a1/a2=b1/b2 but not equal to c1/c2

now

a1/a2=6/k

and b1/b2

10/5=1/2

1/2=6/k

k=1×6/2

k=3

Answer 2

Answer:

answer is 3

as A1/A2=B1/B2=C1/C2
